Healthy skin cells require a constant supply of blood. in decubitus ulcers, or bed sores, this blood supply is hindered because superficial blood vessels are compressed. which layer(s) of the skin hold(s) such compressed blood vessels?

the papillary and reticular layers pf the dermis.

Hope This Helps!

Reticular and papillary layer of dermis.

Explanation:

The blood is the main connective tissue present in the body. Each and every cell of the body requires blood for its activation and blood supplied cells remain healthy.

The bed sores hinders the blood supply because the superficial blood vessels are restricted. The papillary layer of the dermis and the reticular layer of the skin holds the compressed blood vessels in the case of the decubitus ulcers.

Thus, the answer is reticular and papillary layer of dermis.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good

explanation:

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
